Lilium humboldtii grows up to 6 feet (1.8 m) tall, with flowers that are maroon-spotted, golden-orange with dark red splotches, with orange to brown stamens. The plant flowers in June, with flowers growing in a pyramidal inflorescence. The flowers are on stout stems, which are sometimes brown-purple. The subrhizomatous bulb is large, with yellowish-white scales, and grows very deep in the soil. The leaves grow in whorls, and are undulate, shiny, and oblanceolate. It is summer-deciduous, dying back after flowering in mid- to late summer.[2]
Albert Kellogg, unaware that the plant had already been named by Roezl and Leichtlin, gave it the name Lilium bloomerianum. For some time afterward, the name was still applied to the southern California Lilium humboldtii subsp. ocellatum.[4]
Cultivation
Lilium humboldtii is sold as a garden bulb. It prefers dry summer dormancy, with no water after blooming, good drainage, and part shade. It was one of the parents, along with Lilium pardalinum, that produced the Bellingham hybrid lilies, which eventually resulted in the popular 'Shuksan' and 'Star of Oregon' lilies.[2]
